HYDROCARBON-BURNER.

Specication of Letters Patent.

'Application med February 13, 190s. serial No. 415,630.

To all whom it may concern:

Be it known that I, HIRAM C. RUGeLEs, a citizen of the United States, yresiding at Pasadena, in the county of- Los Angeles and State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification'.

This invention relates to a hydro-carbon burner in which steamor compressed air and oil are thoroughly mixed and atomized before leaving the burner, and it consists in the arrangement of the steam 'and oilfchambers and passageways so that `the steam, upon emerging from its chamber will draw along with it a sufficient supply of oil to form a combustible mixture therewith. To this end the steam outlet isv preferably formed in the shape of a nozzle with the oil outlet also in nozzle shape and surrounding the steam outlet. Both of these nozzles are arranged to discharge into a mixing chamber of such a configuration that a circular or gyratory movement is set up whereby the steam and oil are thoroughly mixed with each other, and their atomization completed, before being discharged and burned.

A further novel feature of this burner is its construction in several'distinct parts to form the chambers and passages therein.

I accomplish the above by means of the device described herein and illustrated in the accompanying drawings, in which Figure 1,- is a vertical section of my improved burner. Fig. 2,- is a plan view of the base of the burner, the upper parts being removed. Fig. 3,- is a plan view of the steam nozzle plate. Fig. 4,- is a plan view of the oil nozzle. Fig. 5,-` is'a bottom plan view of the top plate of the mixing chamber.

Referring to the drawings, 10 designates a base which may be made in any suitable configuration and is provided with two,screw threaded inlets 11 and 12 for oil and steam respectively. Base 10 is providedV with a circular portion 13 containing a circular steam chamber 14 in its center and an annular oil chamber 15 around chamber 14. Chamber 15 is connected by a port 16 to oil inlet11, and chamber 14 is connected by a port 17 to steam inlet 12. Centrally disposed in the bottom of chamber 14 is a screw threaded bore 18, adapted to receive abolt 19 which holds the several parts of the burner together. Y

Mounted directly above chambers 14 and 15, and in steam tight engagement with base shown in Fig. l.

lchamber 14 'and concentrically around bolt 19 so that the opening through the nozzle is annular andrestricted. Plate 20 is provided rwith apertures 22 which are disposed directly over annular oil chamber 15, and through which the oil passes upwardly into oil chamber 23 around nozzle 21.

Directly above plate 20 is mounted an oil nozzle plate 24, which is flat on its lower surface, and is provided with a conical nozzle opening 25 in its center, which nozzle is directly above and around steam nozzle 21. The sizeof the oil nozzle is so related to that of the steam nozzle, that the appropriate relative amount of oil Will be carried therethrough by the current of steam which emerges from nozzle 2 1.

Plate 24 is provided in its upper face with a circular concavity 26 which forms the lower half of mixing chamber 27. The upper half of this chamber is formed by a corresponding concavity in the to plate 28, the sectional configuration of the c amber being From this figure it will be seen that the steam and oil enter the mixing chamber near its center and directly around bolt 19. Upon passing upwardly they are deflected and iow along the circular walls of `the chamber, as indicated by the arrows,

and on account of this rapid circulation the steam and oil are thoroughly mixed before passing out of the chamber through burner outlet 29. This burner outlet is formed in the wall of top plate 28 and may extendV bolt 30 is utilized to secure plates 24 and 28.

together and hold outlet 29 open.

In the operation of my improved burner, steam and oil are admitted to the respective inlets in proper quantity from any convenient source of supply. The steam passes upwardly through nozzle 21, and, the opening of this nozzle being restricted by bolt 19, a considerable suction is formed around the nozzle. The oil iiows upwardly into oil chamber 23, surrounding the steam nozzle, and is forcibly drawn through nozzle 25 by the passage of the steam therethrough. The steam and oil together ass uplwardly into mixing chamber 27, where t ey are thoroughly atomized and mixed, as before described. The pressure ofthe steam forces the mixed steam and oil out of the burner through outlet 29 in the form of a thin sheet and a flame is formed Which has a maximum surface in contact With the atmosphere, thus insuring perfect combustion` Having described my invention what I claim as new and desire to secure by Letters Patent is 1- A hydrocarbon burner comprising a base member having a steam chamber therein, a

steam nozzle plate upon the base member, i

the nozzle thereon connected to the steam chamber in the base member, an oil nozzle plate spaced above the steam nozzle to form an oil chamber, the oil nozzle in the plate being directly over the steam nozzle, and a top plate on the oil nozzle plate, the top and oil nozzle plates having a mixingr chamber formed therein.

In Witness that I claim the foregoing l have hereunto subscribed my name this 5th day of February, 1.908.
